characterized in that:
   the connecting means ( 4 ) provides: at least a hooking member ( 5 ) shaped so as to limit a seat ( 9 ) having in section a substantially U shape wherein the connecting counter means ( 5 ) provided in each shelf can be inserted,   said counter means comprising at the angles of each shelf at least a first substantially filiform and vertical member ( 10 A),   said seat ( 9 ) of the hooking members ( 1, 2 ) is sized so as to allow inserting with friction said first filiform member ( 10  A) and so that a tract of said first member remains in contact with the inner surface of said seat when the shelf is connected to the supporting members,   and said counter means ( 5 ) providing at said angled portion ( 10  A) a second portion ( 15  A) apt to abut against an inner face of the supporting members ( 1, 2 ) when the shelves are associated to said members.

The object of the present invention is a shelving system according to the pre-characterizing portion of the main claim.

Shelving systems of the above mentioned kind, in particular for implementing small pieces of furniture with several shelves, for example apt to be used in the bathroom, have been known for a long time. In the known systems it is quite complicated associating the shelves to the side supporting members, in fact the procedure requires a certain manual ability and not always the correct sequence of operations necessary for the assembly is easy to be guessed. An additional drawback of the known systems is linked to the fact that when they are dismantled they are quite bulky, which fact affects negatively the transportation and storage costs.

The object of the present invention is to implement a shelving system simplifying and speeding up the operations necessary for mounting the system itself and in particular simplifying the association of the shelves to the related supporting members. An additional object is to implement a shelving system which, when it is disassembled, is less bulky than the known systems.

These and other objects which will appear evident to a person skilled in the art are achieved by a system in accordance to the features of the enclosed claims.

For a better comprehension of the present invention the following drawings are enclosed by simple way of example and not for limitative purposes, wherein:

FIGS. 1 to 4 and FIGS. 5 to 8 show a shelving system according to the invention represented, respectively, in a schematic, perspective, side, front and top view and in an assembled state ready to be used and in a disassembled state ready for shipment;

FIGS. 9 and 10 show a detail of the system in two distinct phases of the assembly thereof;

FIGS. 11 to 17 show perspective schematic views and in some cases partial views of a plurality of variants of the invention represented in FIGS. 1 to 8.

By referring to FIGS. 1 to 10, they show a first and a second side supporting member 1, 2 for a plurality of shelves 3 implemented with metallic wires constrained therebetween, said supporting members and shelves comprising means 4 and counter means 5, respectively, for connecting removably said shelves to said supporting members. According to the invention the connecting means 4 provides:

-   -   hooking means 5 comprising a first and a second portion 6, 7         (FIG. 9) spaced out therebetween, and connected by a connecting         portion 8 so as to limit a seat 9 having in section a         substantially U-like shape, wherein the connecting counter means         5, provided in each shelf 3, can be inserted,     -   said first and second portion 6, 7 being spaced out by a tract T         substantially equal to the thickness S of the wires 10 of the         shelf 3 provided at the angles of said shelves,     -   and a connecting member 11 apt to connect said hooking means 5         to said supporting members 12 in prefixed positions.

According to the invention the connecting counter means 5 provides a substantially filiform and vertical member 10 A apt to insert in the seat 9 and to come in contact with said portions 6-8 of the hooking member 5. The distance D1 (FIG. 2) between the hooking members 5 for a determined shelf 3, provided on each supporting member 1, 2 is substantially equal (by means of the thickness of the wire therewith the hooking member itself is made) to that of D2 (FIG. 6) between the filiform members 10A apt to insert in said hooking members 5 so as to guarantee a stable connection, without yokes, of the shelves to the supporting members, more in particular, the supporting members 1 and 2 preferably provide a tubular structure having a shape like an overturned U and comprising two uprights 12 connected by an upper crosspiece 13. The connecting means 5 of the shelves 3 provides in prefixed, and equidistant, positions, uprights 12 of the two supporting members 1 and 2, pairs of hooking members 5 spaced out therebetween preferably by a tract R (FIG. 10) having a shorter length than the one of the angular metallic wires 10 apt to engage with said hooking members. These hooking members 5 preferably are implemented by bending the ends of a metallic wire 33 rigidly connected transversally to the uprights 12 of each supporting member 1, 2 in prefixed position, with the hooking members projecting outwardly with respect to said supporting members, that is so that the distance D1 between the ends of the hooking members is greater than that of D3 (FIG. 2) between the uprights 12.

The shelves 13 are advantageously implemented by welding therebetween a plurality of transversal metallic wires 3 A and longitudinal metallic wires 3 B (FIG. 4) so as to implement a structure like a net. The shelves preferably provide a bottom wall 3 C (FIG. 5) and only two side walls 3 D, parallel therebetween, departing and substantially perpendicular with respect to said bottom wall; these side walls are limited on the top by an edge metallic wire 16 (FIG. 9). Preferably, the side walls 3D are provided along the bigger side of the shelves, whereas the smaller sides of the shelves are without side walls. The shelves at the smaller ends thereof provide an extremal transversal metallic wire 15 (FIG. 10) welded to longitudinal wires 3B so that they do not project from the above-mentioned wire 15 which, in all effects, constitutes then the end edge of the shelves 3. The extremal transversal wire 15 comprises a substantially horizontal tract 15 A (FIG. 10) at the ends thereof two vertical tracts depart which form the angular metallic wires 10 A mentioned previously, apt to engage with the hooking members 5.

Advantageously, the connecting portion 15 B between the horizontal tract 15 A of the extremal wire 15 and the vertical tracts thereof is angled and it forms with said horizontal tract an angle A lower than 90°, advantageously equal to about 70° so as to favour the insertion thereof of the vertical tracts of the extremal wire 15 in the hooking members 5.

As shown in FIGS. 9 and 10 for assembling the shelving system it is sufficient to slide the shelves from the top to the bottom, by beating a slight friction, in the related hooking members 5 until the end wire 16 of the side walls abuts (FIG. 10) onto the hooking members 5 themselves by preventing an additional descent of the shelf. In such assembly phase the horizontal tract 15 A (FIG. 10) of the extremal wire 15 of the shelves 3 slides with a slight friction along an inner surface of the uprights 12 of the supporting structure 1, 2 as shown (FIGS. 9 and 10) and, when the shelf is hooked, it remains in abutment against said inner surface, by further stabilizing the system.

It is to be highlighted that the shelves, the supporting members 1, 2 and the related means and hooking counter means 4 and 5 are shaped and sized so that when the shelves 3 are inserted in the related hooking means 5, the portions in contact therebetween of the shelves, of the hooking means and of the supporting ones are in strict contact therebetween so as to avoid yokes among the various shelf components and to make the system stable and not shaky; to this purpose, if necessary, when the shelves are unpacked it is possible varying slightly the tilt angle of the side walls 3D of the shelves 3 with respect to the bottom wall 3C.

Thanks to the fact that the distance D3 (FIG. 2) between the uprights 12 of the supporting structures 1 and 2 is smaller than the distance D2 (FIG. 6) between the side walls 3 D of the shelves (that is that between the filiform members 10 A, apt to insert into the hooking members 5, of the extremal wire 15 of the shelves) when the system is disassembled it is possible housing the supporting members 1, 2 inside the shelves (as shown in FIG. 6). Furthermore, advantageously the thickness of the tubes of the supporting members 1 and 2 is limited with respect to the side walls 3D of the shelves 3 so that when said members are overlapped therebetween they result, however, to be still inside the shelves 3 (FIG. 6). The hooking members 5 in this packaging position of the system pass through the meshes of the side walls 3D of the shelves 3 and they result substantially flush or they are little projecting with respect to the outer surface of said walls (as visible in FIGS. 5 and 6). Furthermore, thanks to the fact that the side walls 3D of the shelves 3 are at least partially elastically connected to the related bottom walls 3C, when the system is disassembled it is possible inserting a shelf into the other one as shown in the FIGS. 5 and 6. Practically, then, as shown in FIGS. 5 to 8, the system, when it is disassembled, has an encumbrance which is substantially defined only by the height of the supporting members 1 and 2 and by the width and the height of the shelves 3, that is an encumbrance which is smaller than 20% than the known systems wherein the supporting members had to be rested onto the upper edge of the side walls of the shelves and/or under the bottom wall.

FIG. 11 shows a first variant of the system according to the invention highlighting that specific shelves according to the invention can be used also to form base planes, that is that the shelves can be used in two positions rotated by 180° one with respect to the other one.

FIG. 12 shows an additional variant of the system according to the invention wherein the supporting members 1 and 2 are without the upper crosspiece 13 described previously, so as to limit the system encumbrance. Moreover, according to this variant the connecting means 4 does not provide any more for each angle of the shelves a pair of hooking members 5, but only one hooking member which for systems with small sizes has resulted to be sufficient to guarantee the necessary stability of the system.

FIG. 13 shows an additional variant of the system according to the invention wherein the supporting members 1 and 2 provide only one upright 20. Preferably, the single upright 20 of a supporting member is connected to the single upright of the other supporting member through a longitudinal crosspiece 21, advantageously plug-connected with an upper end of said uprights 20.

FIGS. 14 and 15 show an additional variant of the system according to the invention wherein the connecting means 4 does not provide any more hooking members shaped like a U and implemented by means of folded metallic wires, but by means of a foil providing the ends folded so as to have in cross section a U shape and thus forming a kind of pocket.

FIG. 16 shows an additional variant of the system according to the invention wherein the supporting members 1 and 2 are shaped like a plane wall 25 and the hooking members like tubular members 24 constrained in a conventional way to the wall itself. At last, one wants to state that the embodiments illustrated so far have been provided by simple way of example and that several variants are possible, all belonging to the same inventive concept, therefore for example the hooking members 5 could provide usual organs apt to allow the positioning thereof removable from the uprights 12. To this purpose the uprights could provide, as shown in FIG. 17, a plurality of uniformly spaced holes and the hooking members 5 could provide, departing from the small bar 33 connecting two hooking members therebetween, pins 23 apt to engage in said holes.
